In her revision on Recent Cyclocypridinae, Karanovic (2011) erected the new genus Keysercypria, endemic of the Neotropical Realm. The aim of this study is to describe and illustrate a new species within the genus recorded from the lower Parana region, according to the recently proposed division of the world freshwater ecosystems (www.feow.org). The new species represents the most southern record of the genus. Samples were taken in December 2008 from a temporary pond covered with macrophytes in Buenos Aires Province, Argentina. The material was collected with a fine-meshed (0.25 mm) hand net. The ostracods were then transferred to 70% alcohol for permanent storage. The specimens were dissected under a stereomicroscope immersed in polyvinyllactophenol. The limb morphology was studied under the light microscope and line drawings were made with the help of Zeiss, Standard 25 stereomicroscope with camera lucida.
